This can result in loss of coverage, issues with reimbursement of medical care, recovery of outstanding insurance premiums including penalties, or loss of entitlements. This article will guide you through the rules and show you how to avoid the most common mistakes.

Key takeaways

Long-term stay abroad means that your participation in Czech public health insurance may terminate if you do not respond in time and correctly – and this has serious financial and legal consequences.
The obligation to register with a foreign health insurance system and to communicate properly with your Czech health insurance company is not always obvious, but mistakes can cost you money, limit your entitlement to healthcare services, or even lead to debt recovery.
The country where you carry out gainful activity (EU/EEA/Switzerland versus a third country), the length of your stay, and your employment relationship determine which rules apply to you – in practice, however, employees and their employers often get this wrong.
Without professional assistance, it is easy to make a mistake that can cost you thousands of Czech crowns or trigger unwanted inspections – ARROWS attorneys in Prague will explain the exact rules for your specific situation.

Who is considered to be in a situation of long-term stay abroad

Long-term stay abroad in the context of health insurance is not defined with strict legal precision in a single regulation, but Czech legislation sets out the conditions for termination of participation in Czech public health insurance. In practice, this term mainly covers the following situations:

Carrying out gainful activity (employment or self-employment) abroad, where you are subject to the legislation of that country.
Relocation for employment to another country (e.g., as part of a transfer within a multinational corporation).
Secondment or long-term project assignments abroad.
Expatriates and remote employees working from abroad for a Czech or foreign employer, if, for social security purposes, they are subject to the legislation of another country. These are not exceptional cases. According to statistics, hundreds of thousands of Czech citizens work or spend extended periods abroad. A much larger share deals with health insurance without legal support and makes mistakes in the process.

Why this matters to your Czech health insurance company

Your Czech health insurance company (whether you are insured with ČPZP, VZP, OZP or another provider) records you for the purposes of your participation in public health insurance. Once it is demonstrated that you are permanently or long-term subject to the social security legislation of another country (e.g., due to gainful activity or permanent residence), your participation in Czech public health insurance usually terminates – even if you remain a Czech citizen.

Participation in public health insurance in the Czech Republic is primarily linked to permanent residence in the Czech Republic or to carrying out gainful activity in the Czech Republic. If you leave to work abroad, you will most likely no longer meet these conditions and will be subject to the legislation of another country, which triggers a chain reaction:

Your participation in public health insurance in the Czech Republic terminates.
You cease to be entitled to healthcare in the Czech Republic, except in cases governed by international treaties or EU coordination regulations.
You lose the ability to claim reimbursement for medicines or healthcare services from the Czech system if you were not insured in the Czech Republic.
If you later return, you will need to register again – and if you failed to meet your notification obligation, the insurer may assess outstanding premiums retroactively, including penalties. We also discuss the practical impacts of work relocations abroad (and the related obligations of both employer and employee) in the article Posting an employee to Austria: How do an employment relationship and a DPP affect the mandatory Austrian wage?.

This situation can rarely be handled without legal advice, because individual insurers apply rules and procedures that may have nuances, and there are exceptions that a layperson has no chance of knowing. ARROWS attorneys in Prague can help you navigate these complex rules and exceptions.

Situation in the EU/EEA/Switzerland versus third countries

If you work in one of the EU/EEA countries or Switzerland, you usually benefit from increased protection because the EU social security coordination regulations apply (Regulations (EC) No. 883/2004 and 987/2009).

Single-insurance principle: You are subject to social security legislation (including health insurance) of only one state. As a rule, this is the state where you physically perform gainful activity (the lex loci laboris principle), under the coordination regulations.
Termination of participation in the Czech Republic: Your participation in Czech public health insurance ends on the day you become insured in another state. You must notify your health insurance company of this fact without delay.
Documents for healthcare in the Czech Republic: For necessary medical care during a temporary stay (e.g., a holiday) in the Czech Republic, you use the European Health Insurance Card (EHIC) issued by your foreign insurer. However, if you continue to reside in the Czech Republic (e.g., cross-border commuters), you must request an S1 form abroad and then register it with your Czech health insurance company. This will entitle you to the so-called yellow card of an auxiliary insured person and to full-scope care.
Return to the Czech Republic: If you return to the Czech Republic and meet the conditions for participation in Czech public health insurance (e.g., starting employment, permanent residence), you will usually register again without a waiting period, because your previous insurance periods in the EU/EEA/Switzerland are fully taken into account.

Practical issue: Many people do not know their rights or obligations and do not obtain the necessary documents (EHIC, S1 form, or the relevant form, e.g., S041 or S1). The result: if they return home for a holiday and need a doctor, they do not have a valid insurance card and must pay for care in cash, or pursue reimbursement from their foreign insurer in a complicated way.

ARROWS attorneys in Prague can help you with the legal interpretation and, if necessary, with communication with insurers.

Working stay in third countries

If you work in the USA, in Asia, in the Middle East, or elsewhere outside the EU/EEA/Switzerland, the rules differ radically:

Insurance does not terminate automatically: Your participation in Czech insurance does not automatically end when you leave for work (the European coordination regulations do not apply here). To avoid having to pay advance payments in the Czech Republic, you must use the mechanism of a so-called long-term stay abroad.
Conditions for deregistration: This stay must last continuously for at least 6 months. Before departure, you must submit a written declaration to your Czech health insurance company and surrender (or invalidate) your insured person’s card.
Need for foreign insurance: During your stay in a third country, you must arrange health insurance there (statutory/system-based or commercial).
The treacherous return to the Czech Republic: As soon as you return, you must re-register with the Czech health insurance company and submit proof that you were health-insured abroad for the entire period of deregistration. If you fail to prove this (or prove only part of the period), the Czech health insurance company will ruthlessly assess outstanding premiums retroactively for the entire period of your absence!

Special case: Employees relocated by their employer

If you are an employee of a multinational company and the company “assigns” you abroad (e.g., to a project), the situation is partly your employer’s responsibility and partly yours:

The employer has a duty to ensure that the correct social security rules (including health insurance) apply to you in accordance with the legislation of the destination country.
You have a duty to prove that you are insured abroad. This is not exclusively the job of the company’s HR department, but also in your own interest.
Documents: For example, in the case of posting to the EU/EEA/Switzerland, your employer should arrange for you a document (e.g., the PD A1 form) confirming that you remain subject to Czech social security legislation. If PD A1 confirms that you are subject to foreign legislation, or if it is a third country, you will receive confirmation of insurance from the local authorities or insurer. These documents are key for communication with the Czech insurer.
Employer’s mistake: The employer is responsible for compliance with social security legislation. If your employer forgets to properly register you in the foreign insurance system or fails to secure the necessary documents, it may be in breach of the law.

In practice, employees often rely on HR to “handle it”, and then find out they were forgotten. ARROWS attorneys in Prague will help you obtain the documents from your employer and submit them correctly to the insurer, or advise you on how to proceed if your employer does not act.

Situation upon returning to the Czech Republic

Returning to the Czech system is not automatic. The insurer will require evidence that you are again genuinely living or working in the Czech Republic (e.g., a lease agreement or employment contract). In addition, if you do not provide confirmation that you were insured abroad for the entire period, the authority may retroactively assess outstanding premiums, including penalties.

Without proper preparation, lengthy administrative delays and financial penalties may arise. We therefore recommend that, already one month before returning, you compile confirmation of the termination of insurance abroad and the documents for new registration in the Czech Republic. Professional handling of the entire agenda will ensure that the insurer accepts you back into the system smoothly and without unnecessary sanctions.

ARROWS attorneys in Prague will help you prepare watertight documentation and represent you in communication with the insurer. With a timely consultation, you will avoid the risk that your return turns into an exhausting legal dispute over alleged arrears. For a smooth registration process, contact us at office@arws.cz.

Possible issues	How ARROWS addresses it
You return without any notification to the insurer: The insurer does not have a clean record of your stay abroad and subsequently seeks to recover outstanding premiums for the period when you were not entitled to coverage in the Czech Republic.	ARROWS will represent you in communication with the insurer and, if necessary, also in proceedings.
You do not have documents proving that you actually lived abroad and were insured there: The insurer asks: “How do we know you were not in the Czech Republic and were insured abroad?” Without evidence, this is difficult to explain.	ARROWS will help you obtain relevant documents (confirmations from a foreign employer/authority, bank statements, lease agreements abroad, etc.).
You do not know what premiums will be assessed after your return: This is only dealt with when you file the application – and some people then ask: “That’s too much, I thought it would be less.”	ARROWS will clarify your insurance category and approximate premiums in advance, as well as options for optimizing premiums.
You do not know the difference between termination of participation in insurance and “erasure”: You want the insurer to “delete” everything, but legally that is not possible. Your record remains; only your participation in insurance ends.	ARROWS will explain the legal reality and ensure that your new registration is carried out correctly.

Social security contributions and pension

Note: Health insurance is not the only issue. The problem of social security contributions and pension entitlements is just as serious.

If you work abroad for a longer period and do not pay social security contributions into the Czech Republic, that period will not be counted towards your insurance record for pension purposes in the Czech Republic. This means:

When you return to the Czech Republic and request the calculation of your old-age pension, it will be calculated based on a shorter insurance period.
As a result, your pension will be lower – sometimes by tens of percent.
EU/EEA/Swiss states do have a unified coordination system for social security, and some third countries have concluded bilateral agreements with the Czech Republic, but you must actively use these mechanisms and secure the required documents.

Example:
If you worked for 5 years in Germany, the Czech Social Security Administration (ČSSZ) will include that period for the calculation of a so-called partial pension only on the basis of an insurance confirmation, which you must request yourself from the German authority. Without submitting these documents, the German insurance period remains “invisible” to the Czech pension system, which can materially affect both the amount and even the entitlement to an old-age pension.

Many Czechs return home only to find that years are missing from their pension record. ARROWS attorneys in Prague can help you understand how to address this during your employment abroad so that your time does not “disappear”.

Tax aspects

Health insurance and social security contributions are only one part of the picture. If you work abroad, you are also affected by:

Tax residence – The Czech Financial Administration (tax authority) wants to know whether you are a tax resident. The rules for determining tax residence are complex and are governed by domestic regulations as well as EU law.
Income taxation – Where do you file your tax return and where is your income taxed? In the Czech Republic or abroad? Specific rules apply here as well, based on international double taxation treaties.
Reporting obligations – If you are a manager or an equity holder in a Czech company, you have specific reporting obligations (e.g., towards the Czech tax office regarding income from abroad).
Permanent establishment – If you work for a Czech company from abroad (e.g., from home in a foreign country), under certain conditions this may qualify as a permanent establishment of the Czech company abroad, which has significant tax consequences for both the employer and you.

ARROWS attorneys in Prague understand both social security and tax aspects – and that is crucial for your case.

Final summary

A long-term stay abroad is not just about a change of address, but a complex legal shift in the areas of health insurance, taxes and pensions. Any mistake in deregistration or in proving insurance coverage may lead to the recovery of substantial premium arrears, severe penalties, or an irreversible loss of years worked for your future old-age pension in the Czech Republic.

Among the most common mistakes are failing to secure the A1 form, underestimating specific rules for countries outside the EU (so-called third countries), or insufficient documentation upon returning to the Czech Republic. These shortcomings regularly cause protracted disputes with insurers and unnecessary delays in re-registration, which can be avoided by timely preparation of the necessary evidentiary documentation.

If you do not want to risk financial losses or legal complications, have your situation assessed by experts from ARROWS, a Prague-based law firm. We will help you map your obligations, prepare watertight documentation, and ensure effective communication with Czech and foreign authorities.

FAQ – Most common questions on long-term work stays abroad

1. When exactly will my participation in public health insurance in the Czech Republic end when I move abroad?
Your participation ends on the day you become insured in another state (through employment or residence). You must notify your Czech health insurance company of this change immediately and provide supporting documents; otherwise, it will continue to record you as a debtor and will recover premiums retroactively. ARROWS attorneys in Prague can assist you with proper deregistration and documentation.

2. I have returned from a business trip and the health insurance company is demanding tens of thousands in insurance premiums. Can I defend myself?
Yes, if you can prove that during the relevant period you were subject to insurance in another country (e.g., with an A1 form) and that you fulfilled your notification obligation. In disputes over outstanding premiums or penalties, ARROWS attorneys in Prague will represent you in communication with the insurer as well as in subsequent administrative or court proceedings in the Czech Republic.

3. I am in the EU/EEA/Switzerland and I have a European Health Insurance Card (EHIC) from my country of employment. Can I buy prescription medicines in the Czech Republic during my holiday without paying?
With a valid EHIC, you are entitled to necessary care and medicines with the same co-payments as locally insured persons. However, if you actually live in the Czech Republic but work in the EU, request an S1 form abroad for full access to care via the so-called yellow card. ARROWS can advise you on arranging the required documents.

4. I am a shareholder in a Czech company and I work long-term in the USA. Do I have to be insured in the USA?
If you work long-term in the USA, you must use the local insurance system there. Your status as a shareholder in a Czech company then entails specific tax and notification obligations in the Czech Republic that are not directly related to health insurance. This administratively demanding situation can be safely resolved with a consultation at ARROWS.

5. I am stopping work in Germany and returning to the Czech Republic. How long does registration with a health insurance company take?
Standard registration takes 15–30 days if you provide proof of the termination of insurance in Germany and of meeting the conditions in the Czech Republic (e.g., an employment contract or permanent residence). If documents are missing, the process can drag on for months. ARROWS will ensure the documentation is complete so that reinstatement of insurance proceeds without unnecessary delays.

6. Can I keep my insurance in the Czech Republic even if I work in England (the United Kingdom)? Will I pay it myself?
If you work in the UK, your participation in the Czech system ends and “voluntary” payments in the Czech Republic are not legally permissible. Once the insurer discovers the situation, it would retroactively cancel Czech insurance and claim outstanding amounts and penalties. For the exact procedure after moving to the UK and deregistering from the Czech system, ARROWS specialists can advise you at office@arws.cz.
